Avatar: The Last Airbender - Minor secondary characters
Book 2: Earth

Fire Lord Azulon
Azulon was the previous Fire Lord who has so far only appeared in the flashbacks
Zuko had in "Zuko Alone." He was the husband to Fire Lady Ilah.
He was the father of Fire Lord Ozai and Iroh, and thus grandfather to Prince
Zuko, Princess Azula, and Prince Lu Ten. He was the son of Fire Lord Sozin,
instigator of the war. Like Iroh, Azulon was apparently a general in the
war years before becoming the Fire Lord and once searched for the Avatar
as Zuko does now. His granddaughter Azula is named after him. Azulon was
the Fire Lord of the Fire Nation for almost twenty-three years until he
mysteriously died about six years ago. Fire Lord Azulon ran the Fire Nation
much like his father did – with an iron fist, and was a frightening
man who demanded perfection. Fire Lord Azulon, like every Fire Lord, was
a master Firebender. In his time, he was considered one of the best in
the world and no one would dare cross him. Despite his strong leadership,
Azulon cared very little for the people of his nation and was more interested
in world domination, a quality he passed down to Ozai. Some of his greater
military successes included the conquest of the Hu Zin provinces in the
Western Earth Kingdom and the Battle of Garsai.

Fire Lord Azulon appears in "Zuko Alone."

Bedouins
More commonly referred to as the "Beetle-headed merchants," these
opportunistic, traveling traders primarily dwell within the Si Wong Desert
and also pre-date all other tribes of the desert. Legend holds that their distinct
beetle-like headpieces date far back to ancient times when their subterraneaous
ancestors managed to wistand the attacks of giant Gilacorns by mimicking the
appearance of the foul-tasting Sour Beetles, the sole creatures on the desert
floor unpalatable to giant lizards. The merchants' flexible nature as well
as their ability to see saleable potential in almost anything presented to
them makes them every tribe's first choice with whom to trade and swap.

The Bedouins appear in "Appa's Lost Days."

The Boulder
A combatant in the Earth Rumble competition, "The Boulder" is a powerful
Earthbender who is a parody of professional wrestlers in general and, more
specifically, The Rock as well as being voiced by veteran wrestler Mick Foley.
Though his "pro wrestling" stage accent may seem unintelligent, he
speaks with a degree of consideration and eloquence that suggests a greater
intellect beneath his bombast wrestler facade. He appears to be a decent human
being at a base level, but is dedicated to winning and competing in the Earth
Rumble tournament. He shows this through his initial reservations about attacking
Toph, a twelve year old blind girl, when she confronts him during the final
round of Earth Rumble VI.

The Boulder appears in "The Blind Bandit." According
to Toph's ransom letter.

Bosco
Bosco, the Earth King's pet bear, is first seen briefly in "City of Walls
and Secrets", when a party is being held for him. After that, he isn't
seen until "The Earth King", once again with a small appearance.
After the Earth King is imprisoned in "The Crossroads of Destiny",
Bosco is watched over by Mai and Ty Lee. Sokka and Toph free the Earth King
and rescue Bosco. Toph Earthbends Ty Lee's limbs into the ground, and Mai simply
isn't interested in fighting and tells them to "just take the bear." He
later escapes Ba Sing Se with his owner, along with Aang and his friends.

Bosco is the Italian word for 'forest.' It is also a chocolate
syrup brand whose icon is a bear.

Chin the Great
A conqueror and warlord born over 370 years ago, Chin was a ruthless tyrant
and managed to take control of most of the Earth Kingdom, save Ba Sing
Se in the northeast and the Kyoshi Peninsula in the southwest. When Chin
demanded that Avatar Kyoshi surrender her homeland to him, Kyoshi instead
split it from the mainland, killing Chin and creating Kyoshi Island. The
village of Chin, located at the split of the Kyoshi Peninsula, is named
in his honor.

Written in ancient Chinese script, at the base of the
Chin the Great statue is his name, (qín wěi),
which literally means "Chin--Great". He is named
after Qin Shi Huang, the first Emperor of China, for whom
the country is named.

Chong, Lily, and Moku
A trio of Earth Kingdom nomads who along with their group travel around land
singing songs to experience the wonders of the world. This trio is probably
meant to be a parody of hippies, as their songs concentrate on the topics
of love and peace.

Chong, his wife Lily, Moku, and two other nomads, who
remain unnamed, meet the kids, who are on their way to
Omashu, and offer to take them through a shortcut to Omashu
known as the Cave of Two Lovers. None of them seem terribly
bright and act somewhat unusually easy-going, which becomes
a source of frustration for the kids, especially Sokka.

They appear in "The Cave of Two Lovers." The
Chinese word for the flower 'lily, translates as 'hundreds
unite,' which is coincidentally one of the goals of a hippie.
Since he somewhat resembles one with his coolie hat, Moku's
name could be variational pronunciation of the Chinese
word for 'mushroom,' mó gu. The word Chóng
can be translated as 'bug,'.

Circus Animal Trainer
First appearing in "Appa's Lost Days", this man is an animal tamer
of a Fire Nation circus, the same that which Ty Lee came from, who used abusive
methods to "break" his animals. He appears to direct his animals using
a fire whip, and has a very short temper. According to the official site, he
once served and was raised by a sadistic Fire Nation nobleman, no doubt from
whom he acquired his abusive nature. The trainer is further described as a formidable
chess player, as well as a soft-spoken loner. The animals that were shown in
the episode that he tamed were Appa, a Vulture Griffin, and a Platypus Bear.

Circus Ringleader
First appearing in "Return to Omashu", this man is the leader of a
traveling Fire Nation Circus. He seems stubborn, but also easily bullied, as
shown when Azula forces him to set fire to a net beneath a performing Ty Lee.
He also appears in "Appa's Lost Days" where he told the tamer to put
the sky bison (aka Appa) in the show. The Ringleader is worried for Ty Lee's
safety when he is forced to set fire to the net beneath her tightrope, so he
cares for some of his employees, especially one of noble blood as Ty Lee.

Dai Li
Selectively picked at a young age, the members of the Dai Li are elite officers
of Ba Sing Se under the control of Long Feng. Their job is to ensure that
no one disrupts the order of the city, such as by speaking of "undesirable" topics
like the war with the Fire Nation. They employ skilled Earthbenders as
a secret police group, who wear gloves made apparently out of earthen materials
in order to dexterously Earthbend on the go. The Dai Li also are adept
at using Earthbending to cling to sheer rock surfaces, such as walls or
ceilings. They conceal chained metal cuffs within their sleeves, which
they use to snare and hold prisoners, particularly other Earthbenders so
as to inhibit their bending.

The Dai Li first appear in "City of Walls and Secrets."

The Earth King
The fifty-second ruler of Ba Sing Se, and indeed the entire Earth Kingdom,
the Earth King makes a cameo appearance in the episode "City of Walls
and Secrets" during a party for his pet bear, Bosco, for whom he seems
especially fond. He makes his first full appearance in "The Earth
King", when Aang and his friends come before him accusing the Dai
Li of treason. Having never left his palace and being told false information
by Long Feng, the king was previously unaware of the war against the Fire
Nation. However, evidence provided by Aang and his group persuaded him,
and he agreed to mount an invasion of the Fire Nation. Unbeknownst to him,
the Dai Li remained loyal to Long Feng.

The name Kuei is a spelling variation on the Mandarin
word for "leader, it may also be a variant of the
word for "puppet", kuî .

The Five Seven Five Society
Directed by the formal Madame Macmu-Ling, the Five Seven Five Society is haiku
club whose membership appears to primarily consist of elegant young ladies
who hail from Ba Sing Se's upper echelon of families. In addition to haiku "slamming",
the society also hosts tea and garden parties. The name of the club is
conspiciously based off the defining syllabic layout of a typical haiku.

The Five Seven Five Society appears within "The Tale
of Sokka" in "The Tales of Ba Sing Se."

General Fong
General Fong is an Earthbender General who is in command of an Earth Kingdom
fortress situated in a mountain range in the western Earth Kingdom. Known
for his unusual tactics and now considered to be one of the most aggressive
officers in the army, Fong originally enlisted as a common soldier twenty-five
years ago, but rose through the ranks to become an officer and eventually
General. Despite being poorly educated, he has gained high recognition
from his superiors for his 'no fear' attitude on the front lines, as well
as loyalty from his troops through the air of equality his less than formal
background provides.

He appears in "The Avatar State." His name likely
a variant of the word fēng (瘋) which translates
as 'insane.' At the end of the episode "The Avatar
State," Aang even commented to him "You're out
of your mind."

Ghashiun
A desert dweller and Sandbender who resides within the Si Wong Desert. He is
the son of Sha-Mo and is the person directly responsible for Appa's kidnapping
in The Library. Ghashiun is an adolescent who normally spends his days
riding around the Si Wong on his sand-sailor with his gang of friends,
usually getting into trouble and stealing anything that isn't well guarded.
According to the official site, Ghashiun has been acting somewhat emotionally
detached ever since his mother, Yulduz, died of skin cancer, a common affliction
in the sun-drenched desert. As demonstrated in The Desert, his relationship
with his father is distant at best with Ghashiun's lying and stealing only
serving to strengthen the rift.

Ghashiun appears in "The Library", "The
Desert", and "Appa's Lost Days", with his
speaking role increasing with each appearance.

Gow
The head of a band of thugs in an Earth Kingdom village, he and his crew bullied
and terrorized the citizens of the town, excusing themselves as Earth Kingdom
soldiers. When Zuko entered the village, they stole the feed he had purchased
and accused him of throwing eggs at them. Zuko did not flinch, though,
and Gow warned him to get out. Later, Gow led his band to Ganzu's homestead.
He informed the farmer that his eldest son, Sen Su, had been captured,
but backed down when Zuko threatened him. Later, Gow kidnapped Lee, Ganzu's
younger son, and refused to surrender him when Zuko commanded it.

Gow is a Scottish surname that derives from 'Gobha,' the
Gaelic for 'smith,' which the character resembles with
his twin hammers.

General How
As leader of the Council of Five, How is essentially the supreme officer of
the Earth Kingdom military and the primary military adviser to the Earth
King. Introduced in "The Earth King", he and his men searched
Long Feng's office, retrieving several documents including a military report
revealing the location of the Southern Water Tribe forces, the scroll from
the Guru, and a letter said to be from Toph's mother. He is loyal to the
Earth King and was therefore conflicted about the war remaining a secret
from him. How and the other Council members were making preparations for
the invasion of the Fire Nation during the solar eclipse when Azula and
the Dai Li captured them as part of their coup in "The Crossroads
of Destiny".

General How first appears in "The Earth King".

Sister Iio
As a Mother Superior, Sister Iio was the female Airbender nun in charge of
the Eastern Air Temple seen in a flashback at the age of 87 during Appa's
Lost Days. She prepared several children, including Aang, to bond with
a group of young Flying Bison. She gives each of them an apple, telling
them how to choose a bison carefully, because a Sky Bison is a companion
for life. Iio is described as an uneffected and cheerful person, and apparently
quite skilled at Airball. Her ultimate fate is unknown, though she likely
died when the Fire Nation destroyed the Air Nomads.

Sister Iio appears in "Appa's Lost Days". Iio
(pron: eye-oh) is a Japanese surname (飯尾)
that literally translates as 'steamed rice fish tail.'

Ilah
Ilah was the wife of Fire Lord Azulon, the mother of Fire Lord Ozai and Iroh,
the grandmother of Lu Ten, Zuko and Azula. Nothing is known about her other
than the facts above. She is deceased at the time of Azulon's funeral.

Ilah is mentioned briefly in "Zuko Alone" at
Azulon's funeral. ʾilāh is the Arabic for 'deity,'
which goes well with the translation of Azula's name as
the Sanskrit word for 'demon,' Asura.

Jin
A citizen of Ba Sing Se who frequently visits the tea shop where Iroh and Zuko
were employed, Jin eventually builds up the courage to ask Zuko out on
a date. After going out to an awkward dinner, the pair go to a fountain
that is renowned for its beauty (and the place where Jin's parents used
to meet as teenagers); however, the lanterns that majestically illuminate
the fountain are unfortunately unlit when they arrive. Noting her disappointment,
Zuko asks Jin to close her eyes and he carefully uses Firebending to light
the lanterns. At the end of their date Jin kisses Zuko. Although he begins
to return it, he then backs away abruptly and excuses himself by saying, "It's
complicated", and he leaves her standing alone.

Jin appears in "The Tales of Ba Sing Se". Jin
is also briefly seen in "The Awakening" inside
the tea shop during the Fire Nation invasion of Ba Sing
Se.

Joo Dee
Introduced in "City of Walls and Secrets", Joo Dee at first appears
to be a stereotypically vapid and ignorant tour guide—despite the fact
that Sokka has information regarding the war against the Fire Nation, she constantly "handles" the
entire group into following her tour, promising them audience with the Earth
King of Ba Sing Se within six to eight weeks. When Aang and the group go searching
for Appa and information dealing with the war on the Fire Nation, Joo Dee hangs
back from the others, ever-smiling. When Sokka asks a question that gets close
to the truth, Joo Dee will smile broadly and shake her head at the person under
interrogation, which elicits a withdrawn, scared reaction from them. When Aang
and the group crash the Earth King's party in a botched attempt to alert him
of the solar eclipse that causes Firebenders to lose their bending power, Joo
Dee urges them to leave before they are caught; but when Aang is exposed as
the Avatar, her perpetual smile melts into something closer to hopeless despair.

Joo Dee appeared in "City of Walls and Secrets" and "Lake
Laogai."

Lao Bei Fong
Lao Bei Fong is Toph's father and a wealthy figure in the village of Gaoling.
He cares deeply for his daughter and only wishes for her safety, but he
is far too overprotective of her, even going as far as hiding her existence
from the rest of the town. His fear for her well being only increased when
he witnessed her mastery of earthbending. When Toph ran away to teach the
Avatar, he assumed she was kidnapped by him and commissioned Xin Fu, the
promoter of the Earth Rumble VI Earthbending tournament, and Master Yu,
Toph's earthbending teacher, to do "whatever it takes" to rescue
her.

Lao appears in "The Blind Bandit." According
to Toph's passport in "The Serpent's Pass" and
the fake letter from her mother in "The Earth King",
Bei Fong is written as 北方 and when put after 老(lào)
translates as 'Old North' or 'Mr. North.'

Lee
Lee is the boy Zuko meets in Zuko Alone. Zuko first meets Lee when he is buying
food for his ostrich horse and himself. Lee and his friends throw some eggs
at the bully Earth Kingdom soldiers, and quickly leave. Seeing Zuko as the
only one around, the guards blame him and take his food. Lee regrets getting
Zuko in trouble and invites him to his house for food. Lee warms up to Zuko,
thinking of him like an older brother, where Lee's actual brother is currently
fighting against the Fire Nation. Lee also reminds Zuko of himself as a younger
child. Late at night, Lee steals Zuko's broadswords and practices with them
in the fields. Zuko wakes and confronts the boy, but instead of scolding him
for the theft or the harm Lee could do to himself, Zuko gives Lee a short lesson
on how to use the broadswords. Before he leaves, Zuko gives Lee his knife,
the one given to him by Iroh and the one used to cut his knot in "The
Avatar State." After a confrontation with the guards once more, Lee pulls
the knife on them and is taken away from his mother. Zuko eventually rescues
Lee from the guards but uses his firebending to do so. After the battle, Zuko
tells Lee to keep the knife, but Lee quickly shuns him away, refusing to take
the gift and saying "No, I hate you!" after realizing Zuko's origins.

Oma and Shu
First mentioned in The Cave of Two Lovers, Oma and Shu were the world's very
first human Earthbenders. Their tombs lie side by side within the walls
of the cave, whose decorated walls tell their story, otherwise known as "The
Legend of the Two Lovers." Oma and Shu were a woman and a man who
met atop a mountain that divided their two villages, two different tribes
who were currently warring with each other. Their love was strong, however,
and they were able to find a way to be together. The two were able to learn
earthbending from the badgermoles that dwelled within the mountain, and
using their bending, were able to carve out elaborate tunnels where they
continued to meet secretly.

Guru Pathik
When met by Appa in "Appa's Lost Days", Guru Pathik understood that
he was not the person Appa expected, and he simply lies back, looking at Appa
every so often, and receiving a growl in return. Eventually, night settles
in, and Appa falls asleep. The Guru reads Appa's Spiritual energy, remarking
on how Appa is so full of love and trust, but at the same time fear is moving
into where trust should be. He also tells of how he had a vision of Aang and
Appa years ago, and decided to come to the Eastern Air Temple and wait for
the two. He then leaves Appa to rest, saying how Appa must let the clouds in
his mind part and be at peace.

A guru is a spiritual teacher. The word 'pathik' means "the
traveler" in Hindi.

Quon
Quon is a wealthy, young, charismatic merchant of Ba Sing Se who hails from a
family of entrepreneurs. He has managed to expand his family fortune by investing
in and starting up several businesses of his own, including Ba Sing Se's first
trans-wall food delivery service designed for Middle and Upper Ring customers.
In "Lake Laogai", after sampling a cup of his brew, Quon persuasively
offers to build Iroh his very own tea shop in the Upper Ring, which Iroh passionately
accepts, and the results of their deal can be seen with the opening of the
elegant "Jasmine Dragon" tea house in "The Guru."

The Rough Rhinos
The Rough Rhinos are a group of Fire Nation soldiers who are currently pillaging
and raiding Earth Kingdom villages like common bandits. They are strong
however, as each of the five members rides a ferocious three horned lizard
and is a master of a different weapon.

The name "Rough Rhinos" itself may be a reference
to the Rough Riders, a nickname given to the 1st U.S. Volunteer
Cavalry Regiment during the Spanish-American War.

Sandbenders
Out in the Earth kingdom's Si Wong Desert, there inhabits a small group of nomads
with a certain proficiency with the discipline of earthbending in regards to
manipulating sand, inherently earning them the nickname of Sandbenders. Little
is known except that they exhibit a tribalist system of organization and make
use of catamaran-like vehicles which they propel with small dust devils of
sand to move about the desert. Since economic opportunities are limited in
the desert, Sandbenders get by however they can. They have been known to scavenge
for dead animals, or even steal from passing travelers at the nearby cantina.
They resemble Bedouins in many ways such as clothing, lifestyle and tribe-system.

Song
Song is a kindhearted girl from an Earth Kingdom village who helps Iroh after
he makes tea out of a poisonous plant thinking it was edible, and subsequently
getting a horrible rash covering his entire body. Song manages to cure him
and then invites him and Zuko to eat dinner at her house. At her house she
talks about the war and how Fire Nation soldiers captured her father years
ago to fight in the war. From Song, Zuko realizes the side effects of war from
the perspective of a common person outside of the Fire Nation and finds empathy
for her. However, Zuko steals an ostrich horse from her family to aid in his
and Iroh's travels; while Song witnesses the whole event, she says nothing.

General Sung
General Sung is in charge of defending the outer wall of Ba Sing Se, the Earth
Kingdom capital city. He originally refused Aang's help in stopping the
Drill that the Fire Nation was using to attack the outer wall, believing
he could handle the situation himself, but humbly requested the Avatar's
assistance after the Terra Team, an elite team of Earthbenders which were
defeated by Ty Lee, failed to destroy the machine. He is also part of the
Council of Five, the Earth King's most trusted generals.

General Sung first appears in "The Drill."

Old Sweepy
Under the guise of a weary but talkative janitor, "Old Sweepy" in
actuality is an undercover agent for the Dai Li who serves to keep close watch
on the Lower Ring and spreads misinformation wherever Long Feng instructs.
Desite his ragged and dreary appearance, he is quite professional as well as
effective in regards to the execution of his duties. Once a top officer of
the Cultural Authority, Sweepy was severely relegated by the Grand Secretariat
into deep cover as a menial laborer after he botched an assignment. Dedicated
to his demeaning position, old Sweepy hopes to eventually win back his favor
in Long Feng's eyes.

Old Sweepy appears in "Lake Laogai."

Terra Team
A platoon of elite Earthbenders that guard the walls of Ba Sing Se commanded
by General Sung. The Terra Team was ordered to destroy the Fire Nation
drill attacking the wall, but were easily disabled by Mai and Ty Lee.

The Terra Team briefly appear in "The Drill." Their
name is clearly influenced by the Latin word "Terra",
literally meaning "earth."

Tho, Due, and Huu
Three members of the Foggy Swamp Tribe. While Momo and Appa are separated from
Aang, Katara and Sokka, they are being hunted by Tho, who is a little short
and chubby, and Due, who is very tall and skinny. The kids, in the meantime,
are being chased after by a Waterbender named Huu (pronounced "Hugh"),
a fat man of average height, who can bend the water in plants and use them
for a swamp monster disguise. Huu, like Aang, heard a voice from the Swamp
and became "enlightened" as he realized that the swamp's illusions
reflect on life, death, the connection between the earth and all its organisms
as a whole and that time is irrelevant. Using this new-found knowledge,
Aang finds Appa and Momo and stop Tho and Due, who are more than happy
to find fellow Waterbenders outside of the Swamp in Aang and Katara.

Tho, Due, and Huu appeared in "The Swamp."

Tycho
A mugger who formerly had high hopes of working at the Spa University in Ba
Sing Se, but was refused aid in paying the tuition and disowned by his
family. In desperation, he fell into a life of crime. In "Tales of
Ba Sing Se", within an alley, Tycho came across and attempted to mug
Iroh, who was on his way to a picnic, but was easily knocked off his "poor
stance" and disarmed within seconds. Rather than have him arrested,
Iroh instead briefly provided instruction towards the mugger on how to
assume a more serious and solid stance. Over a cup of tea, Iroh proceeded
to encourage him to pursue his dream of becoming a masseur. Tycho expressed
great joy over Iroh's advice, stating that he was the first person ever
to truly believe in him.

Tycho first appears as brief cameo in "City of Walls
and Secrets", seen offering a large saber to a man
in an alley.

Princess Ursa
Princess Ursa is the wife of Ozai and mother of Prince Zuko and Princess Azula.
She has only appeared in flashbacks in the episode "Zuko Alone" and
a feverish dream of Zuko in "The Earth King", although not much
is known about her. It is shown that she is very protective of her son
Zuko and may be one of the only members of the Fire Nation royal family
(along with Uncle Iroh) who loves him. Shortly after the death of Iroh's
son, Lu Ten, her husband Ozai asked his father, the Fire Lord Azulon, to
pass Iroh's birthright to the throne to him. Ozai considered Iroh an unworthy
quitter who let the death of his son get in his way of conquering Ba Sing
Se. This dishonorable request only infuriated Azulon, who declared that
Ozai would be fittingly punished for venturing to betray his own brother
in his time of sadness. It is unknown what exactly this punishment was
or if it was even carried out, though Azula told Zuko that it was to have
him killed so that Ozai would know how it felt to lose his own first-born
son. By the next morning, Ursa had disappeared, Azulon was proclaimed dead,
and Ozai was announced as his willed successor. It is unknown what part
Ursa had in these scandalous events, but it is almost certain that she
played a major role in protecting Zuko. In Ursa's final appearance in the
flashbacks, she wakes Zuko before her departure to remind him of her love
and to tell him to always remember who he was, no matter how things seemed
to change.

"Ursa" is Latin for bear, which is likely a
reference to how protective she is of Zuko.

Princess Ursa first appears in "Zuko Alone." In "The
Earth King", the blue dragon (who has Azula's voice)
says "Sleep... just like mother!" referencing
her disappearance. Also, although not seen, Ursa is mentioned
in "The Crossroads of Destiny".

Wan Shi Tong
Wan Shi Tong is the spirit of knowledge, an ancient and powerful being who
knows more than any human walking the earth. Though his normal physical
form is that of an immense black-and-white barn owl, an animal commonly
associated with wisdom in Western thought, Wan Shi Tong is able to lengthen
his body and transform into a feral serpent-like creature when angered.
Thousands of years ago, he built the great spirit library in the pursuit
of preserving all knowledge of the world. Despite his vain persona, in
hopes of sharing the knowledge, Wan Shi Tong brought the structure over
to the mortal plane, placing it within the Si Wong Desert.

Wan Shi Tong appears in "The Library." His name
is a phrase in Mandarin Chinese ("萬事通")
that literally translates to "He Who Knows 10,000
Things."

Xin Fu
The promoter as well as the host of the underground Earthbending tournament,
Earth Rumble VI, Xin Fu seems on the outside a nice enough guy, but when
prompted with the possibility that he has been cheated, his more underhanded
side becomes clear. He kidnapped Aang and Toph when the Boulder suggested
that Toph purposely lost the match to Aang and then split the money with
him afterward. Though Xin Fu is seemingly a powerful Earthbender since
he lasts longest against Toph, he is still defeated. He is then recruited
by Toph's father to retrieve Toph who Aang "kidnapped" by "any
means necessary", and is now pursuing Aang, Katara, Sokka, and Toph
alongside Master Yu. He has also shown that if he catches Aang, he fully
intends to sell him to the Fire Nation for a large monetary reward. He
is shown in The Blind Bandit to be a proficient and powerful Earthbender
as he was once an active competitor of the Rumble.

Xin Fu appears in "The Blind Bandit", "The
Desert", "The Earth King", and "The
Guru." Although partly obscured, his name in Toph's
ransom letter was written as 辛富 (xīn
fù) which translated as 'bitter rich.'

Ying and Tahn
Ying and Tahn, first appearing in Book 2, Chapter 7, "Zuko Alone",
are a married couple that Zuko contemplates stealing food from. However, when
he sees that Ying is pregnant, he decides against it. The couple re-appears in
Book 2, Chapter 12, "The Serpent's Pass," where they are trying to
gain entrance into Ba Sing Se, only to discover that their passport has been
stolen. The gang helped them and Tahn's sister cross the deadly Serpent's Pass
in the chapter of the same name. After they finished crossing, Ying went into
labor and Katara helped deliver her baby. At the time, Aang had been very morose
over Appa's disappearance, but he told Ying that seeing the newborn baby gave
him hope; as a result Ying chose the name Hope for her child. Later, after parting
with the gang, the family make a cameo at the end of "The Drill" inside
the monorail leading to Ba Sing Se where Zuko and Iroh ended up taking a seat
next to them, unaware of any past encounter.

Master Yu
A Master Earthbender who teaches the local children earthbending and provides
private lessons to Toph, but only teaches her the basics (simple breathing
exercises and stances), at the request of her father.

Even though Master Yu is treated with a great deal of
respect, he doesn't seem to be the powerful Earthbender
that everyone treats him as. Although, he may simply be
holding his real skills and knowledge back from his students
so that he doesn't have to strain himself teaching them
as he is shown keeping up with Xin Fu in "The Desert,".

Master Yu appears in "The Blind Bandit", "The
Desert", "The Earth King", and "The
Guru." According to the leaflet from his school in
The Blind Bandit. Yú is a Chinese surname meaning
'surplus' and (shīfù) means 'master' which
as a title is put end of a teacher's name.

Yung the Resistance Leader
Yung formerly was the Captain of King Bumi's army, until Bumi ordered him and
his forces to stand down and surrender the Earth Kingdom city of Omashu
in the wake of a Fire Nation invasion. Yung reluctantly followed the orders
of his King, and afterwards became the leader of the resistance force against
the occupying Fire Nation within the city. Yung was saddened and confused
at what he saw as shamefully surrendering the city without a fight. An
assertive, confident, battle-oriented Earthbender,[1] Yung has clearly
stated that he would have much rather fought the Fire Nation to the death
and lost than to have surrendered to them Omashu as was ordered to. Yung
continues to lead the resistance, planning attacks and trying to remove
the city's rulers from power, in hopes of driving the Fire Nation out and
reclaiming Omashu (later renamed New Ozai by Azula, in honor of her father)
for his people.

He appears in "Return to Omashu".

Professor Zei
He is the head of the Anthropology Department at Ba Sing Se University. Professor
Zei is a well-traveled, highly educated student of exotic cultures. His
thirst for knowledge brings him to strange, remote, and often dangerous
places. A map of his travels shows he's been everywhere in the world, except
the Fire Nation. However, before meeting Aang and his friends, the professor
was unable to fulfill his life work: finding the secret library built by
the spirit Wan Shi Tong and his knowledge seekers. He does find the library
with the help of Aang and his friends. When Wan Shi Tong discovers their
plans against the Fire Nation they had drawn up using his information,
he sinks his library so that his knowledge could never be misused again.
As he and the others try to escape, Zei tries desperately to grab as many
books as he can to take; eventually, though, he simply declares that he
would rather stay "for eternity" than lose his life's work, and
the others are forced to leave without him.

Professor Zei appears in "The Library."

There is only one zéi in Mandarin and it means
'thief,' which is in a way what an archaeologist is sometimes
considered.
